Idina Menzel was one of the guests on
"Live with Kelly and Michael" on Tuesday (Nov. 12). While there, the actress and singer talked about her role in the animated film,
"Frozen," as well as her marriage to fellow actor,
Taye Diggs.

One of the most entertaining parts of the interview came when Menzel talked about her young son. The boy is apparently just as dramatic as his parents. "He's obsessed with
Michael Jackson," Menzel said, showing a photo of her son's Halloween costume. "He's obsessed with zombies and Michael Jackson, so what better than to be in 'Thriller'?"

And yes, he knows the zombie dance.

Menzel and Diggs have actually been a couple since they both appeared in the original cast of
"Rent." Their courtship during the play's run included "sexy" notes left in Menzel's dressing room.
Kelly Ripa revealed that she too had gotten notes from Diggs during the actor's recent appearance on "Live." These were less sexy, more along the lines of "We're out of milk."

The main point of the interview was to promote Menzel's role in the upcoming animated film, "Frozen." She provided the voice for Elsa the Snow Queen, one of two sisters in the movie -- the other being voiced by
Kristen Bell.

"It's kind of a modern take on the two girls. They're not your standard princesses," Menzel said.
